10. The figure shows two loudspeakers (A) and (B), and a point (C) where a listener is positioned. The speakers vibrate out of phase and are playing a 63.0 Hz tone. The speed of sound is 342 m/s. The listener at point (C) hears the third destructive interference (not counting the point at infinity) at a distance 4.00 m as measured from speaker (A). What is the separation (d) between the two speakers? dbg70 dbg70 dbg70 dbg70 dbg7 A d dbg70 dbg dbg70 dbg70 dbg70 dbg70 bg70 dbg70

IS A PIPE 2.95m Long, DETERMINE THE FREQUENCIES OF THE TAKE 334115 FIRST THREE HARMONICS IF THE PIPE IS OPEN AT BOTH ENDS, AS THE SPEED OF SOUND IH ARE; IF THEY WANT TO DETERMINE THE VELOCITY OF SOUND AT DIFFERENT TIME AT TEMPERATURE 20 degREES CELCIUS, WHAT WILL BE ITS VELOCITY? OF CS Scanned with CamScanner

Water from a reservoir flowing through a non rigid 600mm diameter pipe with a velocity of 2.m/s is completely stopped by a closure of a valve situated 1050m from the reservoir. The pipe thickness is 18mm. Bulk modulus of elasticity of water is 2000MPa and modulus of elasticity of steel is 200000MPa. A.) Compute the velocity of soundwave Choices: 1724.47 1442.47 1224.74 2441.74 B.) Determine the pressure due to instantaneous closure (KPa) Choices: 2449.49 4229.94 2994.94 4922.49 C.)Determine the pressure due to a closure that takes place in 5 seconds. in KPa Choices: 408 804 840 480 Note:please help me in the sample problem and please base ypur answer on the given choices thank you

I need the answer as soon as possible
